Ferritin vs. Hemoglobin

Ferritinnoun

(protein) Any of a family of iron-carrying globular protein complexes consisting of 24 protein subunits.

Ferritinnoun

a protein containing 20% iron that is found in the intestines and liver and spleen; it is one of the chief forms in which iron is stored in the body

Ferritin

Ferritin is a universal intracellular protein that stores iron and releases it in a controlled fashion. The protein is produced by almost all living organisms, including archaea, bacteria, algae, higher plants, and animals.

Hemoglobinnoun

The iron-containing substance in red blood cells that transports oxygen from the lungs to the rest of the body; it consists of a protein (globulin), and haem (a porphyrin ring with an atom of iron at its centre).

Hemoglobinnoun

The normal coloring matter of the red blood corpuscles of vertebrate animals. It is composed of hematin and globulin, and is also called hæmatoglobulin. In arterial blood, it is always combined with oxygen, and is then called oxyhemoglobin. It crystallizes under different forms from different animals, and when crystallized, is called hæmatocrystallin. See Blood crystal, under Blood.

Hemoglobinnoun

a hemoprotein composed of globin and heme that gives red blood cells their characteristic color; function primarily to transport oxygen from the lungs to the body tissues;

Hemoglobin

Hemoglobin, or haemoglobin (spelling differences) (from Greek αἷμα, haîma 'blood' + Latin globus 'ball, sphere' + -in) (), abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells (erythrocytes) of almost all vertebrates (the exception being the fish family Channichthyidae) as well as the tissues of some invertebrates. Hemoglobin in blood carries oxygen from the lungs or gills to the rest of the body (i.e.
